Circular light spot compensation and correction mechanism for laser cutting

The invention discloses a circular light spot compensation and correction mechanism for laser cutting, and relates to the related technical field of laser cutting, the circular light spot compensation and correction mechanism comprises an equipment base, and a feeding case and a cutting case which are arranged at the top of the equipment base, and the feeding case and the cutting case are connected through a connecting frame on the same rail; according to the pipeline laser cutting device, when a pipeline is subjected to laser cutting, the distance between the laser cutter and the pipeline to be subjected to laser cutting can be adjusted by moving the tooth plate and the laser cutter, and at the moment, the spot size of a laser beam emitted by the laser cutter can be controlled by adjusting the position; according to the laser cutting device, laser cutting can be conducted on pipelines made of different materials in a matched mode, the quality and attractiveness of the pipelines cut through laser are guarante
